Subsonic .223 with Titegroup

But honestly, rather than making assertions or statements from "feels" or "thinks", go read a few reloading manuals and educate yourself. You'll be better off for it, and truly enjoy reloading and experimenting.
 
Regarding powder burn rates. It's less to do with barrel length than it is with controlling the pressure from ignition to bullet leaving the barrel (leave aside semi automatics, because they add more nuance).

I don't have time to get into an essay about it but PLEASE don't go comparing a given charge in .22LR with one in .223. The case volumes are far too different. That .22LR also uses a soft lead bullet that is lighter than the typically jacketed .223.

I ran into problems years ago using "The Load", which involved a light charge of Red Dot behind a cast bullet in .308.

One shot felt just like every other, except I had to hammer the bolt open, and found the primer pocket had just about doubled in size - no doubt one of those random high pressure events that you can get with small charges of fast powder in a large case.

What I'm saying is that you need to be careful. In fact if you're a new reloader you shouldn't even be playing with strange recipes
 
Thanks for the advice.

Although I hoped I could find some way around it, I'm going to have to rent a chronograph before I go to the range to shoot a set of reduced loads that starts off with 3.5 grains downward. I should know within a very few shots what amount of Titegroup will propel a Campro 55-grain fmj out of a 9.5" barrel to obtain a speed of between 900 and 1,000 fps.

Thanks again.

Sight in your rifle at 40 metres and try to get a drop of 7 inches at 100 metres you will probly be around 1000fps if your scope is 1.5 inches above bore

Interesting...might have to try some some .308 now. Also this has got me thinking about trying .22 Hornet level loads since I have a bunch of 4227 powder.

Hey barry , what is the report on 4227

I have been told to use it as Black Powder replacement . 3 1-2 gr of 4227 instead of 20 gr Blk Pwdr in cartridges
